The hemoglobin molecule is composed of four chains of amino acids: two alpha chains and two beta chains. The start of the code of the beta chain is GTGCACCTGACTCCTGAG. This codes for the first six amino acids of this chain: valine-histidine-leucine-threonine-proline-glutamic acid. If a single nucleotide polymorphism (SNP) occurs in the code for glutamic acid, which of the following will be a consequence of the SNP?
A. it will result in a different amino acid replacing glutamic acid
B. it will result in glutamic acid replacing all six amino acids at the start of the beta chain
C. it will result in the amino acids present after glutamic acid in the beta chain being replaced by different amino acids
D. it will result in glutamic acid replacing all amino acids in the beta chain
A. it will result in a different amino acid replacing glutamic acid
